SPECIFICATION forming part of Letters Patent N9. 371,818, dated Olctober 18, 1887. Application filed May 23, 1887. Serial No. 239.106. (No model.)

To all whom it may concern: Y

Beit known that I, J ULIUs BRUUN, a subject of the King of Denmark, residing at Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in Lubricating Apparatus; and I do declare the following to be a full, clear, and exact description others skilled in the art to which it appertains ro to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. Figure 1 is a front view of my improved lubrcating apparatus. Fig. v2 is a vertical,s ectional view on line A B, Figli. Fig. 3 is a front viewof the distributing-disk. Fig. 4 is a front view of a modified form of the apparatus. Fig. 5 is a vertical sectional view on 2o line A b, Fig. 4; and Fig. 6 is a' front view of "the distributing-disk of this .form of apparatus. s

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation toautomatic lubricating apparatus; and it consists in the improved construction and combination of parts of such an apparatus, as hereinafter more fully described and claimed.

In the accompanying drawings,`the letter a: indicates the-stand of the apparatus, which stand supports theoil cup or reservoir c at its upper' end, and this stand is A,formed .with a bearing at its middle, in which the shalt r is 3 5 journaled. i A ratchet-wheel, u, -slides upon and turns with the shaft,- and is engaged by a pawl, f', pivoted upon a rocking lever, f 2, having its fulcrum upon the side of a circular face or projection, y, tric with the bearing of the same. The rear end of the shaft is providedwitha washer having spring-arms z, which bear against the rear face of the ratchet-wheel, and this washer is held upon the shaft by means of a nut, z2. -A cylinder, S, having two bores, s, one in each end, is secured upon or is integral with the forward end of the shaft, and hasa circular face, y', which fits against the circular fce or projection ofthe stand, and thisface upon the 5o cylinder is drawn to bear perfectly tight against the face of the standby the springwasher, which draws the shaft rearward.K

of theinvention, such as will enable upon the stand concen-4 Two pistons or plungers, a, reciprocate in suitable stalling-boxes in the ends ofthe bores of the'cylinder, and the endsof the plungers are connected by means of a rod, e, parallel to theplungers and extending at the forward side of the cylinder, sliding in a bearing, k, upon the middle of the: cylinder.

A ring, g. is secured to the stand concentric with the shaft, and the ends of the plungers bear against th'e inner edge of this ring, fol'` lowing the contour ,of the same, and as onehalf of the inner edge of the-ring is raised inward, as shown at g', forming a segmental j shoulder or rib, the plung'ers will be reciprocatedwhennthe cylinder is revolved within the ung; Y- W,..- Y The c linder has channels v' extending from `its bores to the circular face at diametricallyopposite points of the same, and the ends of these channels register with two semicircular' grooves, 'vandv6 in the face or projectionof the stand, the. said grooves having, respectively, channels 'vs and fu? opening into them.Y The first-named of these' channels extends into a tap, d, into which the pipe conveying the oil to the part of the engine or machine to be oiled is'secured,while the last-named channel extends upward to the oil cupor reservoir. lt will now'be seen that as the cylinder`is revolved with the shaft, which is revolved through the mediumof the rocking bar and the ratchet-wheel, the plungers will he reciprocated and willalternatel'y draw oil into them through the channel registering with the groove having the connecting-,channel v3 to the oil-cup, the opposite cylinderat the same time forcing oil into the groove having the channel extending into the pipe, so that the oilsupply will be kept up while the machine or .engine is in operatlon.v

A modified form of theiiibricamr is shown ingFigs. 4, 5, and 6, in which the channel extending from the ol-cup opens directly in the face of the circular faceor projection of the stand, while the channel carrying off the oil opens into a circular groove.extending from both sides of the discharge-port, and the cylinder is only formed with one bore and with one plunger, the end of which is secured in a cross-piece, t, having two parallel-rods, t', ex-

tending from its ends. rlhe other ends ,of these rods slide in perforations in the ends of a tionary and sliding cross-piece.

" edge of the cam-ring is provided with as houlthe cylinder,

der, p, at its lowermost point, and it will be seen that when the cylinder is revolved the taps will s1ip oi`1c from the shoulder when arriving at that point, so that when the tap or stud`at the end of the plunger slips oli' the shoulder the plunger will be drawn out, drawing oil into the bore of the cylinder through the registering-channels of the bore andv of the stand, while vat all other points of the ring the plunger will gradually be forced into the bore by the spiral or gradually inwardlycurving edge of the ring, forcing oil into the circular groove, and from that to the machine part to be lubricated.

This lubricator will be found useful with steanrengines for the purpose of forcing oil into the cylinder and valve-chest, and the rocking operating-lever may be connected to any reciprocating portion ofthe engine or machine, and may either be reciprocated both Ways by the said connection or it may be raised by the engine and tilted down by a suitable weight upon its end.

l Having thus described myinvention, Iclaim and desire to secure by Letters Patent of the United States- 1. `In a lubricating apparatus, the combination of a stand having an inlet and an outlet channel, an'oil cup or reservoir-secured at the inlet, arotary shaft journaled in the stand, havinga cylinder upon its end and having a channel registering with the inlet and outlet channels,a reciprocating plunger within and a cam-ring upon the stand, the inner edge of which engages with and op'- erates the plunger, substantially as and for the purpose set forth. v

2. Ina lubricating apparatus, the combination'ofastand having a circular projection at one side, and provided with suitable discharge channelsand ports, and having a bear'- ingat the center of the projection, a shaft journaled in said bearing, having a cylinder at its end, said cylinder being provided with .a port registering with the port and channels of thestand and adapted to bearagainst the projection of the stand,-a reciprocating plunger within the cylinder, a ratchet-wheel sliding upon and revolving with the shaft, a washer upon the end of` the shaft,having spring-arms adapted to bear against the ratchet-Wheel, and a nut for securing the washer, substantially as and for the purpose l set forth.

3. In a lubricating apparatus, 'thecombination of a stand, a rotary shaft journaled in the stand, a' cylinder upon one end of the shaft, provided with a suitable inlet and outlet channel, a reciprocating plunger within'the cylin-v and a circular projection concentric with the bearing and formed with two semicircular grooves having a connection, respectively, with the oil-cup and with a discharge-pipe, a shaft journaled in the bearing in the' stand, a cylinder upon the end of the shaft, formed with two bores and a circular face, y', and havingchannels opening into it from the boresand regis tering with the grooves in the face of the stand, and plungers reciprocating in the bores ofthe cylinder and having means for rccip- `rocating them as the cylinder is revolved, su bstantially as and for the purpose set forth.

5. In a lubricating apparatus, the combination of a stand, a shaft journaled therein, having a cylinder upon its end, said cylinder being provided with bores in its ends, plungers in the bores of the cylinder, a rod parallel With the cylinder for `connecting the plu ngers, and a carnring having a cam or projection extending one-half of the inner edge of the ring and engaging with and operating the plungers, substantially as and for the purpose set forth. f

6. In a lubricating apparatus, the combination of a stand having a bearing at its middle, and provided with a circular face or projection, y2, concentric with the bearing, and

formed with semicircular grooves, an oil-cup and an outlet-pipe connected with said grooves, a shaft in the bearing in the stand, having a ICO cylinder at one end, said cylinder having two l bores in its 'ends and provided with channels extending to the -face of the circular disk of the cylinder and registering with the grooves in 'the Vprojection y2, a ring secured to the face of the stand concentric with the bearing, and having one-half of its inner periphery formed with a seniicircular cam or projection,
